From 02984cc7b3d62418bd72abacaf875c3a9eccdb66 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Thu, 8 Jun 2017 16:15:06 +0300 Subject: [PATCH] IB/core: Enable QP creation with a given source QP number Enable QP creation with a given source QP number. The created QP will use the source QPN as its wire QP number. This comes as a pre-patch for downstream patches in this series to allow user space applications to accelerate traffic which is typically handled by IPoIB ULP.
